In 1248 Louis IX of France sailed for Egypt in 36 ships with an army of 15,000 that included 3000 knights and 5000 crossbowmen. It was the beginning of the Seventh Crusade. The goal was to establish a base in Egypt and eventually recapture Jerusalem from the Muslims. While in Egypt they fell under attack by the Egyptian army who over several years nearly wiped out the entire French army in the end (1254).
Magistra Hersend of Paris, a female surgeon traveling with the army, was one of King Louis’s royal surgeons. She also took care of the Queen and the camp civilians as they followed the army on land. As brutal and life threatening as the fighting must have been, Magistra survived the ordeal. In return for her service, the king gave her a pension for life of twelve pence a day (or one shilling). She also married the king's apothecary.
